Refrigeration system.
Background technique
The compressor that constant speed air-conditioning system uses is constant speed drive, in this way, when indoor heat load is less than the system of compressor
When cooling capacity, compressor constantly start and stop could must maintain the constant of room temperature, and the frequent start-stop of compressor makes
Refrigerating efficiency of the air-conditioning system in sub-load reduces, annual energy efficiency decline.
Meanwhile existing air-conditioning system mostly uses greatly capillary, electric expansion valve, heating power expansion valve etc. as throttling member
Part, and these restricting elements in compressor shutdown without the ability complete switched off.Therefore, when compressor is just out of service
When, on high-tension side refrigerant will flow to rapidly low-pressure side by restricting element, make on high-tension side high temperature refrigerant and low-pressure side
Low-temperature refrigerant mixes rapidly, and the high-low pressure of air-conditioning system quickly reaches the state of complete equipilibrium.
However, although the complete equipilibrium of high-low pressure is conducive to being again started up and (will not generating starting impact) for compressor,
But have lost the refrigerating capacity or heating capacity of air-conditioning system.For example, in cooling mode, when compressor is just shut down, evaporation
Refrigerant in device is still within the state of low-temp low-pressure, still has certain sweat cooling ability, will evaporate if at this moment
High-temperature high-pressure refrigerant balance in low-temperature low-pressure refrigerant and condenser in device, then undoubtedly just have lost this portion in evaporator
Divide refrigerating capacity possessed by refrigerant.In a heating mode the case where, is similar, and what is only at this moment lost is evaporator
In refrigerant heating capacity.
Waste cold or waste heat when in order to make full use of compressor shutdown in indoor heat exchanger (i.e. evaporator), further mention
The annual energy efficiency of high air-conditioning system can block between indoor heat exchanger and outdoor heat exchanger in compressor shutdown
Pipeline, while keeping the operating of indoor blower.In this way, since the pipeline between indoor heat exchanger and outdoor heat exchanger is hindered
Disconnected, the refrigerant in outdoor heat exchanger cannot be mixed with the refrigerant in indoor heat exchanger immediately, the refrigeration in indoor heat exchanger
Agent in a period of time after compressor shutdown just still have supply waste cold (in cooling mode) or supply waste heat ability (
Under heating mode), so as to by the air circulation of indoor blower, continue to indoor cooling supply or heat supply for a period of time.
The refrigerant blocking of high and low pressure side is commonly used in compressor shutdown in air-conditioning system in the related technology
Method is a fluid path solenoid valve of connecting between the outdoor heat exchanger and restricting element of refrigeration system.For example, in refrigeration mode
Under, when the compressor is operating, fluid path solenoid valve is kept it turning on, and refrigeration system continues refrigerating operaton；When compressor is out of service,
Fluid path solenoid valve is accordingly turned off, and refrigerant flow path is cut off at this time, the low-temperature refrigerant in the heat exchanger that can make to stay within after
Continuous supply waste cold.
However, since fluid path solenoid valve is mounted on the main fluid path of refrigerant, flow through the flow of fluid path solenoid valve valve port compared with
Greatly, it is desirable that the valve body of fluid path solenoid valve must be very big, and biggish fluid path solenoid valve higher cost, so that entire air-conditioning system
Cost greatly increases.Further, since this method is the pipeline completely cut through between indoor external heat exchanger in compressor shutdown,
High and low pressure cannot be balanced, therefore in compressor restarting, biggish starting will can be brought to rush to compressor
It hits, thus may be only available for the compressor insensitive to switch DP (such as screw compressor with flexible scroll plate), and
It cannot be used for the rotor-type compressor that staring torque is small, sensitive to switch DP.In addition, the pressure balance that some compressors use
Device installation is inconvenient, globality is poor and higher cost.

22 → gas-liquid separator of heat exchanger 40 → throttle valve, 50 → indoor heat exchanger, 30 → third, 23 → second interface of interface 60 → sucking
Mouth 102, is thusly-formed complete refrigeration cycle.Under refrigeration cycle mode, the refrigerant in outdoor heat exchanger 40 is in high pressure
Condensing state, the refrigerant in indoor heat exchanger 30 are in low pressure evaporating state, and the two sides of throttle valve 50 are in larger pressure difference shape
State, therefore, the state that No leakage heating power expansion valve is on and normally throttles.
When refrigeration system 1 is in heating circulation pattern (reversal valve 20 switches to heating state), refrigerant is in compressor
Circulating path outside 10 is then: 30 → throttle valve of outlet 103 → first interface, 21 → third, 23 → indoor heat exchanger of interface 50
→ outdoor heat exchanger 40 → the 4th 60 → suction inlet of interface 24 → second interface, 22 → gas-liquid separator 102.In heating cyclic module
Under formula, the refrigerant in indoor heat exchanger 30 is in high pressure condensing state, and the refrigerant in outdoor heat exchanger 40 is in low pressure steaming
The two sides of hair-like state, throttle valve 50 are in larger pressure differential condition, and therefore, No leakage heating power expansion valve is on and normally throttles
State.
As shown in Figure 1, first flows to the coil blackout of control piece 410, first-class when compressor 10 is just out of service
It being connected to control piece 410, the pressure in shell 100 is the low pressure equal with the pressure at suction inlet 102, second interface 22, the
The cut-off of one check valve 421；Simultaneously as No leakage heating power expansion valve valve port when compressor 10 is shut down is closed, thus by high temperature
The refrigerant partition of the refrigerant and low-temp low-pressure of high pressure mix the two cannot mutually in the two sides of No leakage heating power expansion valve
It closes.
In this way, still being remained in outdoor heat exchanger 40 and indoor heat exchanger 30 after compressor 10 can be made full use of to shut down

10 pressure at expulsion and pressure of inspiration(Pi) sufficiently balances, and compressor 10 is avoided to start with pressure difference.
It is illustrated respectively with freezing and heating two kinds of situations below:
When refrigeration system 1 is in refrigeration cycle mode, compressor 10 and just shuts down, since compressor 10 is no longer persistently to system
Cryogen compressed action, the pressure difference between outdoor heat exchanger 40 and indoor heat exchanger 30 will decline, when pressure difference drops to No leakage heat
When the cutoff pressure of power expansion valve, No leakage heating power expansion valve will end.
Since first flows to the conducting of control piece 410, the high-pressure refrigerant in shell 100 will flow to control piece by first
410, gas-liquid separator 60, second interface 22, third interface 23, then release stress to the indoor heat exchanger of low-pressure side 30, most
Make that the pressure in shell 100, the pressure at air entry 211, the pressure of refrigerant tends to be equal in indoor heat exchanger 30 afterwards, i.e.,
All in low-pressure state.

Simultaneously as it is low-pressure state that shell 100 is interior when shutting down, and the refrigerant in outdoor heat exchanger 40 is still high pressure shape
State, the first check valve 421 will end, and the high-pressure refrigerant in outdoor heat exchanger 40 cannot be flowed back by the first check valve 421
In shell 100, thus by temperature still higher high temperature refrigerant barrier in outdoor heat exchanger 40, and by the still lower system of temperature
Indoors in heat exchanger 30, high temperature refrigerant and low-temperature refrigerant cannot be mixed mutually, and then be stopped in compressor 10 for cryogen barrier
The heating efficiency of high temperature refrigerant and the heat absorption capacity of low-temperature refrigerant are remained when machine respectively.
At this point, if indoor blower 80 is still being run, so that it may take away the cooling capacity in indoor heat exchanger 30, to continue
Cooling room air, takes full advantage of the waste cold in indoor heat exchanger 30 in this way, can effectively improve the refrigeration season of refrigeration system 1
Energy saving source efficiency ratio, keeps refrigeration system 1 more energy saving.
When refrigeration system 1 is in heating circulation pattern, compressor 10 is just shut down, since compressor 10 is no longer persistently to system
Cryogen compressed action, the pressure difference between outdoor heat exchanger 40 and indoor heat exchanger 30 will decline, when pressure difference drops to No leakage heat
When the cutoff pressure of power expansion valve, No leakage heating power expansion valve will end.Due to first flow to control piece 410 be connected, shell 100
Interior high-pressure refrigerant will flow to control piece 410, gas-liquid separator 60, second interface 22, the 4th interface 24 by first, then
It is released stress to the outdoor heat exchanger 40 of low-pressure side, finally makes the pressure in shell 100, the pressure at air entry 211, outdoor
The pressure of refrigerant tends to be equal in heat exchanger 40, i.e., all in low-pressure state.
The exhaust resistance of cylinder 210 is significantly reduced in low-pressure state in shell 100, compressor 10 is avoided to open again
Occur the compressors such as excessive starting current, difficulty in starting, shock and vibration 10 when dynamic and start phenomenon with pressure difference, is conducive to extend pressure
The service life of contracting machine 10.
Simultaneously as it is low-pressure state that shell 100 is interior when shutting down, and the refrigerant in indoor heat exchanger 30 is still high pressure shape
State, the high-pressure refrigerant in indoor heat exchanger 30 cannot be flowed back into shell 100 by the first check valve 421, thus by temperature
Still higher refrigerant obstructs in heat exchanger 30 indoors, and by the still lower refrigerant barrier of temperature in outdoor heat exchanger 40
In, high temperature refrigerant and low-temperature refrigerant cannot be mixed mutually, and then remain high-temperature refrigeration respectively when compressor 10 is shut down
The heating efficiency of agent and the heat absorption capacity of low-temperature refrigerant.
At this point, if indoor blower 80 is still being run, so that it may take away the heat in indoor heat exchanger 30, to continue
Heating indoor air takes full advantage of the waste heat in indoor heat exchanger 30 in this way, can effectively improve the heating season of refrigeration system 1

When, flow path of the refrigerant in compressor 10 is: refrigerant is from suction inlet 102, second one-way valve 422,211 quilt of air entry
Cylinder 210 is sucked, cylinder 210 is discharged from exhaust outlet 212 in pressure rise after refrigerant is compressed in cylinder 210；Cylinder is discharged
210 refrigerant reaches the upper space in shell 100 by the gap between stator module 310 and shell 100, then via row
103 discharge compressor 10 of outlet.
When refrigeration system 1 is in refrigeration cycle mode, circulation of the refrigerant of compressor 10 outside compressor 10 is discharged
Path is: 103 → first interface of outlet 21 → the 4th interface 24 → outdoor heat exchanger, 40 → throttle valve, 50 → indoor heat exchanger
30 → third interface 23 → second interface, 22 → gas-liquid separator, 60 → suction inlet 102, is thusly-formed complete refrigeration cycle.?
Under refrigeration cycle mode, the refrigerant in outdoor heat exchanger 40 is in high pressure condensing state, the refrigerant in indoor heat exchanger 30
In low pressure evaporating state, the two sides of throttle valve 50 are in larger pressure differential condition, and therefore, No leakage heating power expansion valve is on
And the state normally to throttle.

Check valve 422 is off state, and the low pressure refrigerant in indoor heat exchanger 30 cannot flow back into shell by second one-way valve 422
In 100, thus by temperature still lower refrigerant barrier indoors heat exchanger 30, and by the still higher high temperature refrigerant of temperature
In outdoor heat exchanger 40, high temperature refrigerant and low-temperature refrigerant cannot be mixed mutually for barrier, and then when compressor 10 is shut down
The heating efficiency of high temperature refrigerant and the heat absorption capacity of low-temperature refrigerant are remained respectively.
At this point, if indoor blower 80 is still being run, so that it may take away the cooling capacity in indoor heat exchanger 30, to continue
